i IMPROVEMENT IN BOTTLE-STOPPERS.

. Specification forming part of Letters Patent No. 9,527. (lltd Jilllul'y 4, 1553- To all whom it may concern:

Be it known that I, WALTER HUNT, ofthe city, county, and State of New York, haveinvented a new and useful plan of a Decanter- Stopper, which I designate as the Swivel- Gap Decanter-Stopper, of which the following is a full and exact description.

Said stopper is composed of two parts or pieces-viz., a tube combiningin onepiece two iianges or annular disks with a central vertical shaft having radiating arms at its base, which extend horizontally and unite with the inner periphery of said tube a little below the upper flange or lip of the same, as shown in the elevated cut section, Fig. 3, and the top view, Fig. 2, in the annexed drawings, where similar letters refer to the same parts throughout.

A indicates the tube; B, the upper or lip fiange; O, the bottom flange; D, the shaft; E, the spokes or supporting-arms, F, the cap. The other portion of said stopper is a funnelshaped cap, F, having a 'central perforation sufficiently large to allow it to fall down over the shaft E, as shown in Fig. l, cut section, Fig. 3, and entire view, Fig. 4, which exhibits the stopper opened as in the act of discharging. The cap having been placed upon the shaft while the tube is in the lathe, the orifice at its apex is partially closed by means of a burnish in the hands ot' the turner, to prevent it from coming off over the ball on the summit ofthe shaft, and at the same timeallow the requisite play when the stopper is in a horizontal position for the cap to slide forward, and conse quently separate from the lipflange B, as shown in Fig. 4, thereby producing an opening sufficiently large for the requisite discharge from the bottle in which it is inserted; and, again, when raised to a vertical position (as shown in Fig. l inserted in the neck of the decanter) it falls back and closes the opening efectually by its own gravity, in which two positions it operates as a self opening and closing stopper, colnbining at the same time one or more important advantages over any other plan in use-viz., a perpendicular discharge from the tube-thereby effectually obviating the unpleasant and wasteful results of other plans of pouring aside or over the glass or receiving-vessel. In addition, this plan combines the extremest simplicity wit-hout a single obj ect-ion.

I am aware that there have been other plans of self-acting Stoppers recently introduced. I allude to the bivalves hinged at the top, which, in short, is nothing more than the valve of the treacle-cup duplicated, and its application to 'rum instead of molasses. rIhere are also other plans of recent date, which have sprung up since mine were commenced, constructed upon the principle of puppet-valves, all of which have the same objection of producing an uncertain, scattering, or over discharge, and are constructed upon principles widely different from my above-described plan, and to which I make no claim in this application; but

Wfhat I do claim, and desire to secure by Letters Patent in my above-described invention, 1s-

The combination of the circular cap F and the central shaft, E, upon which said cap is suspended, so as to allow of its having three principal motionsviz., the swivel, pendulous, and sliding` motions-by means of which, without regard to which side of the stopper is upward, (when it is placedhorizontally, or nearly so,) the under portion of the cap swings o from the flange O, thereby producing a downward opening between the two for the requisite discharge of the liquids contained.

VALTER HUNT.
